Abstract
The described embodiments include a computing device with one or more asynchronous circuits and control circuits that control the operation of the asynchronous circuits. In some embodiments, the control circuits are arranged in a hierarchy with a top-level control circuit atop the hierarchy and one or more local control circuits lower in the hierarchy. In these embodiments, the top-level control circuit processes operating information for the one or more asynchronous circuits and/or other functional blocks in the computing device to determine an operating state for the computing device. Based on the operating state, the top-level control circuit communicates commands to the local control circuits to cause the local control circuits to operate in corresponding operating modes. Based on a corresponding operating mode command, each local control circuit sets one or more operating parameters for corresponding asynchronous circuits (and/or one or more other functional blocks).
